Some ARMv4 processors don't support suspend, which leads to a build failure with the tegra and qualcomm cpuidle driver: WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n] Selected by [y]: - ARM_TEGRA_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_TEGRA [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y] arch/arm/kernel/sleep.o: in function `__cpu_suspend': (.text+0x68): undefined reference to `cpu_sa110_suspend_size' (.text+0x68): undefined reference to `cpu_fa526_suspend_size' Add an explicit dependency to make randconfig builds avoid this combination.
